Abstract

Méthode pour la production d'un polycarbonate aromatique, consistant à introduire dans une zone d'entrée (munie d'une plaque perforée) : a) un mélange monomère fondu d'un composé aromatique dihydroxylé et un carbonate diarylique, ou ; b) un prépolymère obtenu par réaction d'un composé aromatique dihydroxylé avec un carbonate diarylique. On laisse ensuite le mélange monomère ou le prépolymère à l'état fondu descendre à travers la plaque perforée et tomber librement dans une zone de polymérisation à chute libre, la polymérisation du mélange monomère ou du prépolymère s'effectuant lors de la chute. On produit ainsi des polycarbonates aromatiques incolores et de grande qualité, de façon stable et à un taux élevé de polymérisation pendant une période de temps prolongée, à l'aide d'un appareil possédant d'excellentes propriétés de scellage sous un vide poussé, et facile d'entretien.
